This has been discussed before on this list, without a particularly
satisfying answer:

This is still a problem, but looks unsolvable as far as I can tell. The
closest you can come, as far as I can tell, is using what Matt Watson
demonstrated in this script:
https://lists.webkit.org/pipermail/webkit-gtk/2015-September/002429.html That
works as long as you don't try to scroll too fast; in which case the widget
quite obviously lags behind the div with the red background.
